Numrich Parts Lunchbag Letdown

[RCEMERalf]

I ordered some Canadian and L1A1 parts. The Cdn C1 rear sight spring is a joke-too wide, too thin, too short and indented in the wrong place. The L1A1 front sling swivel bands accept a screw one side, but not the other. Should'nt these be threaded on one side? Mossberg 810 action screw, too long for front, too short for rear. Received 2, not 3 cocking handle pivot pins in heavily used condition. I will be processing a return.
I could use 4 front sling swivel bands that do not have the, " wings" but a rectangular projection at the top front that limits rotation. I expect I am not likely to get Canadian ones. Are there others that are similar? Thanks for listening. I feel better already.
